Security Pipe

To get to the New Plymouth Marina, you would need to go out on one of the breakwaters at Port Taranaki. About halfway out there is this weird security gate. It really is just a large pipe with a closed top and two sections cut out of the sides to make a couple doors. As I was drawing it, some boatie arrived at the front with a couple of bags to take on board his boat. He put them down and unlocked the door. He then picked up the bags, entered and closed the door behind him. From my point of view, I could barely see the gangway on the other side that leads down to the floating wharves. It gave me the impression that he was entering his tiny windowless apartment or that this pipe has some sort of Doctor Who Tardis quality where it is much roomier on the inside.
